Description

本発明は、自動車の両車輪のハブベアリングユニットと定速度ジョイントとの軸方向継ぎ手に関する。   The present invention relates to an axial joint between a hub bearing unit and a constant velocity joint of both wheels of an automobile.

車輪のハブが溝付きの継ぎ手を通して定速度ジョイントのベルから駆動トルクを受ける構成は、特許文献1や特許文献2から知られている。そのために、ハブ上に固定されているのは、軸方向外側の目立て部を持つリングである。この目立て部は、定速度ジョイントの外側パーツ即ち“ベル”の軸方向内側の目立て部を持つ管状突起内に挿入される。目立てされたリングと管状突起の双方には、弾性のある開放型ロッキングリングが嵌入される円形溝がそれぞれ設けられている。この弾性リングは、その端部にアームを持つ。このアームは、ジョイントベルの軸方向外側の端部(即ち中心を離れた端部)に形成されたスロットを通して突出している。特許文献1の図5に描かれているのは、シール用弾性スリーブであり、これは、その一端において、ジョイントベルの管状突起の外側円筒形表面上に位置決めされて、前記スロット及びロッキングリングの端部アームの外側からカバーし、そして他端において、ハブの端部に固定された環状パーツ、特にベアリングのシール用装置のインサートとシール状態で協同する。   A configuration in which a wheel hub receives driving torque from a bell of a constant speed joint through a grooved joint is known from Patent Document 1 and Patent Document 2. Therefore, what is fixed on the hub is a ring having a sharpening portion on the outside in the axial direction. The sharpening portion is inserted into a tubular projection having a sharpening portion on the axially inner side of the outer part of the constant velocity joint, ie the “bell”. Both the sharpened ring and the tubular projection are provided with circular grooves into which an elastic open-type locking ring is fitted. This elastic ring has an arm at its end. The arm protrudes through a slot formed at the axially outer end of the joint bell (ie, the end away from the center). Illustrated in FIG. 5 of US Pat. No. 6,057,056 is an elastic sleeve for sealing, which is positioned at one end on the outer cylindrical surface of the tubular bell projection of the joint bell so that the slot and locking ring Covering from the outside of the end arm and at the other end cooperates in a sealed manner with an annular part fixed at the end of the hub, in particular with an insert in a bearing sealing device.

殆ど効果のないシールは、水が、特にジョイントベルの端部に形成されたスロットを通して、溝付きの界面ゾーン中に浸透することを許容する。溝付きの継ぎ手の界面に形成された錆は、ハブベアリングユニットを定速度ジョイントから取り外す操作を特別困難にする上、これら部材の寿命を短縮する。特許文献3は、定速度ジョイントのベルをハブベアリングユニットに対して軸方向に接続するための弾性材料製の環状コネクタを開示している。このコネクタは、ベアリングレースとジョイントベルの双方にそれぞれ形成された溝にスナップ式に嵌入する2つの突起と、ハブとジョイントベルの間を延びて振動を減衰させる第3の突起とを持つ。   The almost ineffective seal allows water to penetrate into the slotted interface zone, especially through a slot formed at the end of the joint bell. Rust formed at the interface of the grooved joint makes the operation of removing the hub bearing unit from the constant speed joint particularly difficult and shortens the life of these members. Patent Document 3 discloses an annular connector made of an elastic material for connecting a bell of a constant speed joint to a hub bearing unit in an axial direction. This connector has two protrusions that snap into grooves formed in both the bearing race and the joint bell, and a third protrusion that extends between the hub and the joint bell and attenuates vibration.

この発明の目的は、定速度ジョイントとハブベアリングユニットとの間の改良された軸方向継ぎ手を提供して、これら2つのユニットの組立及び分解を容易にすると同時にシールに関して上記で論じられた問題を解決することにある。この発明のもう1つの目的は、駆動トルクをジョイントとハブベアリングユニット間で伝達する部材のいくつかの機械加工を単純化することにある。   The object of the present invention is to provide an improved axial joint between the constant velocity joint and the hub bearing unit, facilitating the assembly and disassembly of these two units while at the same time solving the problems discussed above with respect to the seal. There is to solve. Another object of the present invention is to simplify some machining of members that transmit drive torque between the joint and the hub bearing unit.

以下で良好に理解されるこれらの及び他の目的及び利点は、この発明の第1の形態に従い、請求項1に記載された継ぎ手構成によって達成される。この発明のもう1つの形態によると、請求項9に記載された特徴を持つコネクタが提供される。更に別の形態に従い、この発明は、請求項15に記載されたハブベアリングアセンブリを提供する。   These and other objects and advantages, which are better understood below, are achieved according to a first aspect of the invention by a joint arrangement as claimed in claim 1. According to another aspect of the invention, there is provided a connector having the features set forth in claim 9. According to yet another aspect, the present invention provides a hub bearing assembly as claimed in claim 15.

この発明の2つの好ましい、しかし限定的なものではない実施形態が、添付図面を参照して以下で説明される。   Two preferred but non-limiting embodiments of the invention are described below with reference to the accompanying drawings.

シール層40,41,42が定速度ジョイントとハブベアリングユニットとの間の界面を密閉封止して、水や他の汚染物が入ることが防止される。先の種類の通常開放型弾性ロッキングリングの端部アームへのアクセスを許容するために、何らのスロットも管状突起22に機械加工されることがない。更には、ジョイントベル及び駆動リングの対面する軸方向スプラインと交差する従来の円形溝を機械加工することは最早必要とされない。   Seal layers 40, 41, 42 hermetically seal the interface between the constant velocity joint and the hub bearing unit, preventing water and other contaminants from entering. No slot is machined into the tubular protrusion 22 to allow access to the end arm of the previous type of normally open elastic locking ring. Furthermore, it is no longer necessary to machine a conventional circular groove that intersects the axial splines facing the joint bell and drive ring.

後記図2に示された代替実施形態では、ジョイントベル20からハブ10への駆動トルクは、ハブの中心空洞を通して、即ち後記図1に18で示した種類の駆動リングなしに、より多くの通常の溝付き継ぎ手19,23によって伝達される。本発明は、後記図2に示される種類の継ぎ手に対しても等しく適用可能である。   In the alternative embodiment shown in FIG. 2 below, the drive torque from the joint bell 20 to the hub 10 is more normal through the central cavity of the hub, i.e. without a drive ring of the kind shown in FIG. The grooved joints 19, 23 are transmitted. The present invention is equally applicable to the type of joint shown in FIG.

最初に図1を参照すると、自動車両の駆動車輪用のハブ10は、ベアリングユニットを介して自動車両の懸架基準(図示せず)に回転可能に搭載されている。このベアリングユニットは、前記基準に対してボルト(図示せず)を介して固定されたフランジ13を持つ外側固定レース12を有する。ハブ10上にロックされているのは、ベアリングユニットの2組のボール15,16の一方に対する内部レースウエイを形成する内側ベアリングレース14である。ハブは、その軸方向外側の端部に向かって円筒形表面17を持つ。この円筒形表面上には、駆動リング18が固定されている。この駆動リングは、駆動トルクを定速度ジョイントのベル20からハブへ送るための外側軸方向スプライン19を持つ。駆動リング18は、ハブの端部エッジ21の冷間形成によって、好ましくは軌道ローリングによって、内側ベアリングレース14に接して固定的に軸方向にロックされている。   Referring first to FIG. 1, a hub 10 for a driving wheel of a motor vehicle is rotatably mounted on a suspension reference (not shown) of the motor vehicle via a bearing unit. The bearing unit has an outer fixed race 12 having a flange 13 fixed to the reference via bolts (not shown). Locked on the hub 10 is an inner bearing race 14 that forms an inner raceway for one of the two sets of balls 15, 16 of the bearing unit. The hub has a cylindrical surface 17 towards its axially outer end. A drive ring 18 is fixed on the cylindrical surface. The drive ring has an outer axial spline 19 for sending drive torque from the constant velocity joint bell 20 to the hub. The drive ring 18 is fixedly axially locked against the inner bearing race 14 by cold formation of the end edge 21 of the hub, preferably by track rolling.

ジョイントベル20は、その軸方向外側の側面において、内側軸方向スプライン23付きの管状突起22を形成する。このスプラインは、駆動トルクをハブへ送るために、駆動リング18の外側スプライン19と結合する。   The joint bell 20 forms a tubular protrusion 22 with an inner axial spline 23 on its axially outer side surface. This spline couples with the outer spline 19 of the drive ring 18 to send drive torque to the hub.

駆動リング18とジョイントベル20は、環状コネクタ30によって、軸方向に取り外し可能に結合されている。シート鋼製であることが好ましいコネクタ30は、半径方向内側方向に延びたフランジ31と、ジョイントベル20の円筒形外側表面25の回りを軸方向に延びて、そこにスナップ式に接続された半径方向外側の部分とを持つ。   The drive ring 18 and the joint bell 20 are detachably coupled in an axial direction by an annular connector 30. The connector 30, preferably made of sheet steel, has a radially inwardly extending flange 31 and a radius extending axially about the cylindrical outer surface 25 of the joint bell 20 and snapped thereto. With the outer part in the direction.

内側フランジ31は、内側ベアリングレース14と駆動リング18との間に軸方向にシール状態でクランプされた半径方向最内側の周辺パーツ32を持つ。最内側周辺パーツ32の2つの対向する側面は、エラストマー材料の層40,41によってそれぞれ覆われている。これらの層は、一方の側では、内側レース14とフランジ31との間に、また他方の側では、駆動リング18と同フランジ31との間に、軸方向に挿入された状態を保つ。エラストマー層40,41は、フランジ31の2つの対向する側面上に加硫処理された薄い環状ディスクの形態であることが好ましい。   The inner flange 31 has a radially innermost peripheral part 32 clamped in an axially sealed manner between the inner bearing race 14 and the drive ring 18. The two opposite sides of the innermost peripheral part 32 are covered by layers of elastomeric material 40 and 41, respectively. These layers remain axially inserted on one side between the inner race 14 and the flange 31 and on the other side between the drive ring 18 and the flange 31. The elastomer layers 40, 41 are preferably in the form of thin annular disks that are vulcanized on the two opposite sides of the flange 31.

図1に示された例では、フランジ31の内側周辺パーツ32を収容するために、内側ベアリングレース14に面した駆動リング18の側面に周辺円形凹部34が形成されている。環状コネクタ30は、これがハブの円筒形表面17上にスリップされる前に、駆動リング18の凹部34に仮に嵌入され、その後ハブのエッジ21をローリングすることによって、内側ベアリングレース14に接して軸方向にロックされる。1つの変形(図示せず)によると、図1に描かれたものの代替例として、周辺凹部34を設けないことがある。これにより、フランジ31の最内側パーツ32は、リング14及び18間にクランプされたままとなり、それらを互いに僅かに軸方向に離隔された状態に保つ。   In the example shown in FIG. 1, a peripheral circular recess 34 is formed on the side of the drive ring 18 facing the inner bearing race 14 to accommodate the inner peripheral part 32 of the flange 31. The annular connector 30 is pivoted against the inner bearing race 14 by temporarily fitting it into the recess 34 of the drive ring 18 before it is slipped onto the cylindrical surface 17 of the hub and then rolling the edge 21 of the hub. Locked in direction. According to one variant (not shown), the peripheral recess 34 may not be provided as an alternative to that depicted in FIG. This leaves the innermost part 32 of the flange 31 clamped between the rings 14 and 18 and keeps them slightly spaced apart from each other in the axial direction.

別の環状シール層42は、内側フランジ31と後述される軸方向に延びた部分を接合する円錐区間36上に加硫処理されている。   Another annular seal layer 42 is vulcanized on the conical section 36 that joins the inner flange 31 and the axially extending portion described below.

コネクタ30の軸方向に延びた部分は、少なくとも1つの半径方向内側に延びた突起37を持つ円筒形区間35を備える。突起37は、ジョイントの管状突起22の外側円筒形表面25上に形成された円形溝24にスナップ式に係合する結合手段を与える。この溝25によって構成された結合座は、代替例として、異なる形状の凹部か、あるいは凸部でもよい。   The axially extending portion of the connector 30 includes a cylindrical section 35 having at least one radially inwardly extending protrusion 37. The protrusion 37 provides a coupling means for snapping engagement with a circular groove 24 formed on the outer cylindrical surface 25 of the tubular protrusion 22 of the joint. As an alternative, the coupling seat constituted by the groove 25 may be a concave portion having a different shape or a convex portion.

軸方向に延びた部分は、軸方向内側方向に広がる円錐形端部区間38を有することが好ましい。これは、ハブベアリングユニットへのベルジョイントの挿入及びスナップ式ロッキングを好み、またアンロッキングツール(図示せず)に対するアクセスを好む。このツールは、矢印Aの方向に押し込まれて環状コネクタ30を広げ、突起37を溝24から解放し、従ってハブベアリングユニットを定速度ジョイントから離脱させる。   The axially extending portion preferably has a conical end section 38 that extends axially inward. This favors the insertion of a bell joint into the hub bearing unit and snap locking and favors access to an unlocking tool (not shown). This tool is pushed in the direction of arrow A to widen the annular connector 30 and release the protrusion 37 from the groove 24, thus detaching the hub bearing unit from the constant velocity joint.

突起37は、円形リブや、多数の円周方向に整列された歯からなる。円筒形及び円錐形区間35,38は、円周方向に連続しているか不連続である。この後者の場合、それらは、部分的又は全体的に、円周方向に離隔された複数の片持ち式アームからなり、全体として、円周方向に不連続な表面を規定して、突起37の半径方向の拡張と溝24からの離脱を容易にする。   The protrusion 37 is formed of a circular rib or a plurality of teeth aligned in the circumferential direction. The cylindrical and conical sections 35, 38 are continuous or discontinuous in the circumferential direction. In this latter case, they consist of a plurality of circumferentially spaced cantilevered arms, generally defining a circumferentially discontinuous surface, and Facilitates radial expansion and disengagement from the groove 24.

端部区間38は、多数の円周方向に等角度離隔された半径方向開口39を形成する利点がある。これら開口は、ハブの回転を検出するために、懸架基準によって搬送されて開口39に面するセンサ(図示せず)用の音ホイール又はエンコーダとして機能する。   The end section 38 has the advantage of forming a number of circumferential openings 39 spaced equiangularly in the circumferential direction. These openings function as a sound wheel or encoder for a sensor (not shown) conveyed by the suspension reference and facing the opening 39 to detect hub rotation.

シール層40,41,42が定速度ジョイントとハブベアリングユニットとの間の界面を密閉封止して、水や他の汚染物が入ることを防止していることが観察されるであろう。この説明の導入部分で論じられた種類の通常開放型弾性ロッキングリングの端部アームへのアクセスを許容するために、何らのスロットも管状突起22に機械加工されることがない点が認められるであろう。更には、ジョイントベル及び駆動リングの対面する軸方向スプラインと交差する従来の円形溝を機械加工することは最早必要とされない。   It will be observed that the sealing layers 40, 41, 42 hermetically seal the interface between the constant velocity joint and the hub bearing unit, preventing entry of water and other contaminants. It will be appreciated that no slot is machined into the tubular protrusion 22 to allow access to the end arm of a normally open elastic locking ring of the type discussed in the introductory portion of this description. I will. Furthermore, it is no longer necessary to machine a conventional circular groove that intersects the axial splines facing the joint bell and drive ring.

図2に示された代替実施形態では、ジョイントベル20からハブ10への駆動トルクは、ハブの中心空洞を通して、即ち図1に18で示した種類の駆動リングなしに、より多くの通常の溝付き継ぎ手19,23によって伝達される。本発明は、図2に示された種類の継ぎ手に対しても等しく適用可能である。図示のように、コネクタ30は、半径方向内側のフランジ31を有し、その半径方向最内側の部分32は、内側ベアリングレース14と、好ましくは軌道ローリングによって内側レース14に接して冷間形成されたハブの端部エッジ21との間に、シール状態でクランプされ且つ軸方向に固定的にロックされている。37で示されているのは、継ぎ手の歯、又は図1のそれと同様の継ぎ手のリブである。   In the alternative embodiment shown in FIG. 2, the drive torque from the joint bell 20 to the hub 10 is greater than the normal groove through the central cavity of the hub, i.e. without a drive ring of the type shown in FIG. It is transmitted by the joints 19 and 23. The invention is equally applicable to the type of joint shown in FIG. As shown, the connector 30 has a radially inner flange 31 whose radially innermost portion 32 is cold formed in contact with the inner bearing race 14 and preferably the inner race 14 by track rolling. The end edge 21 of the hub is clamped in a sealed state and is fixedly locked in the axial direction. Shown at 37 is a joint tooth or a joint rib similar to that of FIG.

定速度ジョイントをハブベアリングユニットに接続する、この発明に係るコネクタ装置の第1実施形態の軸方向断面図である。1 is an axial cross-sectional view of a first embodiment of a connector device according to the present invention in which a constant velocity joint is connected to a hub bearing unit. この発明の第2実施形態の、図1のそれと同様の図である。It is a figure similar to that of FIG. 1 of 2nd Embodiment of this invention.
